HEADLMIGHT LENS.

Application led November 29, 1926. Serial No. 151,463.

rIhis invention relates -to a lamp for a motor vehicle or the like, the general object of the invention being to provide an improved lens for the lamp which will prevent glare While enabling the driver of the vehi.

lso that the rays of light passing through this rim portion will clearly illuminate the road and enable the driver to see curves.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically .pointed out in thel appended claim.

In describing my invention in detail, refernce will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in whichr- Figure l is a front View of the improved lamp. 1

Figure 2 is a section on line 2 2 of F igure 1.

. In these views, 1 indicates the casing of the lamp and 2 the reflector thereof` these parts belng of the ordinary or any desired construction. 3 indicates the lens which has its major central portion of concavo-convex shape, as shown at 4, and with a rim portion 5 which is of curved construction to provide a-n annular rib around the portion 4, the rib being of substantially U-shape in cross section, as shown. This rib portion is of clear glass while the portion 4 is of white lass. The outer edge of the rib portion is astened to the casing by the clamping means 6 which also hold the reflector in place. The

usual lamp 7 is carried by the reflector and therays' of this lamp are deiiected by the lens 3 so that they will pass through the rib 5, though some of the rays from this lamp will pass through the lens. A lamp 8 is carried by the socket 9 which is placed at the center of the lens 3 and the outer half of this lampq is also colored white, as shown at l0. VThe two lamps are placed in the same circuit, as shown by the conductors 11.

It will thus be seen that the device Will give an brilliant White light which is surrounded by the ordinary light rays passing through the clear rib portion so that the road will be fully illuminated without producing avglare to interfere with the drivers of other cars or pedestrians approaching the car with the improved device thereon. The rib part also acts to throw the light so that the driver can see where he is going on a curve as well as on straight portions of the road. i

It is thought from the foregoing description that the advantages and novel features of my invention Will be readily apparent.

lI desire it to be understood that I may combination and arrangement of the several parts, provided that such changes fall within the scope of the'appended claim.

What I claim is A lamp of the class described comprising -a casing, a reflector therein, a lens at the FREDERICK W. BUTTSCHA;
